Your Inboard M1 trucks might be too stiff or too loose based on your body weight and personal preference.
It is best to test ride your inboard M1 first before tightening or loosening your trucks.
Ideally, you want your trucks tight enough to handle straight line speed, while still giving you freedom to engage rail to rail.
By using the Inboard skate tool, you and adjust the stiffness of looseness of the trucks.
This will give you the best combination of speed and maneuverability around obstacles and carving.
Over tightening trucks is common and should be avoided at all times. You can easily observe your trucks and the bushings of the trucks as extremely compressed.
